Human Factors Ground Test Assessment and Protocol Development for Space Radiation Protection Concepts

Abstract

Human factors evaluations and procedures were developed in a series of ground tests in order to assess novel radiation protection concepts developed by industry leaders in aerospace. In addition, NASA’s current prototype space radiation protection vest and storm shelter concept were tested using the newly drafted human factors assessment materials. Evaluation procedures and wearable garment technology were tested at Johnson Space Center (JSC) using a small sample of current NASA crewmembers for garment testing. Results for the garment analysis indicated that the current radiation vest ultimately did not hinder task performance or impede mobility. Results from the storm shelter analysis indicated that crew were able to construct the shelter within the time allotment without difficulty and limited reference to instruction materials. These data will be used to further develop wearable garment technology and storm shelter designs. Newly developed procedures will be used in future ground tests to further assess novel radiation protection concepts.
